What Is a Tebibyte?
A tebibyte is 1,024 gibibytes or 1,099,511,627,776 bytes. The actual usable capacity shown by operating systems. Try the how many PiB in Zettabytes.
The tebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Related: how many Exabits Per Second in a Tibps.
Common uses: OS-reported drive capacity, NAS actual storage, enterprise storage systems Check out our calculate TiB to KiB.
1 TiB = 9 × 10¹² bits = 1 × 10¹² bytes.
The tebibyte can be abbreviated as TiB; for example, 1 tebibyte can be written as 1 TiB.
What Is a Petabit?
A petabit is 1,000 terabits or 10^15 bits. Used for measuring massive network throughput. Learn more: KiB to Pb conversion rate.
The petabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: converting Gigabytes to Exbibytes.
Common uses: Internet exchange points, submarine cables, global network traffic You might also need: Zettabytes Per Second in Kibibytes Per Second.
1 Pb = 1 × 10¹⁵ bits = 125 × 10¹² bytes.
The petabit can be abbreviated as Pb; for example, 1 petabit can be written as 1 Pb.

SI Decimal vs Binary: Why Two Different Standards?
When converting tebibytes to petabits, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Why Does My Hard Drive Show Less Space Than Advertised?
This difference in standards explains the common "missing hard drive space" confusion.
Example: A "500 GB" Hard Drive
- Contains exactly: 500,000,000,000 bytes
- macOS (SI Decimal): Displays 500 GB (divides by 1,000³)
- Windows (Binary): Displays 465 GB (divides by 1,024³)
The Verdict: Same bytes, same drive—just different math. No space is actually missing.
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
💡 Storage Engineer Tip
The ~9.95% difference between binary and decimal units compounds at each level. A 1 TB drive shows as 931 GiB in Windows because of this standard mismatch—no space is actually lost.
